Differential device of the limited slip type

摘要

The device comprises first (1) and second (2) planet wheels having a common axis, first (4) and second (5) pairs of first satellite gear wheels meshing respectively with the first and second planet wheels, the two gear wheels of each of the said pairs being rotatable on a differential housing (6) coaxial with the planet wheels (4, 5) and having axes lying respectively in first and second planes orthogonal to one another and passing through the first-mentioned said common axis; the device further includes two pairs of second satellite gear wheels (9) also rotatable on the differential housing and having axes lying in the same plane orthogonal to the first and second first-defined planes, each of the second satellite gear wheels (9) meshing simultaneously with one of the said first satellite gear wheels belonging to the first pair (4) and with one of the said first satellite gear wheels belonging to the second pair (5) in such a way that drive can be transmitted from one of the said first satellite gear wheels of one of the said pairs (4, 5) simultaneously to two of the said first satellite gear wheels of the other of the said pairs through a pair of the said satellite gear wheels (9).
